tre of the other. Body beneath hairy on the sides ; hair shorty 

 prostrate, cinereous; last segment of the abdomen and tail yellow, 

 ish. On the sea beach of New Jersey; numerous. 



[Afterwards described by Dejean as C. signata. — Lec] 

 4. C. HiRTicoLLis. — Dull brownish-cupreous, beneath green ; 

 trunk and head with cinereous hair ; lip white ; [21] outer margin of 

 each elytron white with two abbreviated bands, and an interme- 

 diate refracted one ; trochanters purple. 

 Inhabits North America. 



Head coppery, varied with green and blue. Labrum and base 

 of the mandibles white. Thorax very hairy, impressed lines blue . 

 Elytra punctured irregularly with green, a marginal lunale at base , 

 the extremities of which are almost equally prominent ; the' band is 

 divaricated on the margin so as to join the anterior lunule, but it is 

 interrupted before the terminal lunule, abruptly refracted at the 

 centre of the elytron and curved near its termination, towards the 

 suture. Body beneath green, very hairy. 

 Length rather more than half an inch. 



Common in Pennsylvania, very much resembles C trf/asctaki, 

 for which it is probable it has generally been mistaken. 



[This description is very indefinite, but the expressions ' thorax 

 very hairy,' and ' band divaricated on the margin so as to join the 

 anterior lunule,' lead me to refer it to our common sea shore spe- 

 cies afterwards described as C. alhohirta Dej.; the figure given by 

 Say in the Transactions of the American Philosophical Society 

 (infra) represents perfectly that species. It does not live within 

 the limits of Pennsylvania, though on the banks of rivers beyond 

 the Mississippi it is occasionally seen. — Lec] 



5. C. PUSiLLA. — Above black, obscure ; elytra with two lunules 

 and a recurved band, white. Body beneath black -blue, or green- 

 ish. Trochanters testaceous. 



Inhabits with the first. [Kansas and Nebraska.] 

 Elytra with a marginal lunule at base and another at the tip, 

 both very narrow and white ; an intermediate band, divaricate on 

 the margin, recurved at the middle of the elytron and terminating 

 near the suture behind. Labrum and base of the mandibles 

 whitish ; the four basal joints of the antennae purple. 



Length not quite half of an inch. Found by Mr. Nuttall. The 

 band is often obsolete, or only detached portions of it are visible, 

 the enlarged marginal part is permanent. [22]
